DS4700 Express serial number, machine type, and model tag from the faulty
cage frame assembly to the Repair Identification (RID) tag on the new cage
frame assembly. The RID tag is important in transferring the serial number,
machine type, and model from the faulty cage frame assembly to the new
cage frame assembly. Ensure that the new RID tag is affixed to the new cage
frame assembly before you dispose of the faulty cage frame with midplane
assembly. This will ensure that the warranty coverage is not interrupted.
